The prevailing theory is called cladistics. This relies on unique homologies, or structures which members of the clade possess to the exclusion of all other clades. For example, all mammals give milk (the females, anyway) and no other animal gives milk, so mammals are a distinct clade, in this case, a "class." Smaller distinctions determine that certain creatures belong in smaller clades, called "orders," "families," "genera" and "species."

Modern taxonomists use a range of evidence to classify organisms, including morphological characteristics, genetic information, behavior patterns, and ecological roles. DNA sequencing has become an essential tool, allowing for more accurate and detailed classification of species based on genetic similarities and differences. Other sources of evidence may include physiological data, biochemical markers, and fossil records.

∙ 10y agoFour types of evidence used by systematic toxonomists are:
1 Embryological development- cell fate in tissue differentiation - hox regulation
2 physical homology between analogous anatomic features
3 genetic homology between shared expressed genes or protein homology, often using mtDNA but also chromosome synteny (gene order on chromosome) in comparing whole genomes
4 Ecological niche, behavior, biogeographic distribution- biochemical, physiological, or behavioral characters may be at least as good as anatomical characters for discriminating between closely related species.

What is used by modern taxonomists to determine evolutionary or ancestral relationships among taxa?
Modern taxonomists use a combination of molecular data, morphological characteristics, and phylogenetic analyses to determine evolutionary relationships among taxa. Molecular data, such as DNA sequences, provide valuable information on genetic similarities and differences, while morphological characteristics help to identify common ancestry based on physical traits. Phylogenetic analyses, including constructing phylogenetic trees, are used to visualize and interpret these relationships.
Tool used to identify organisms already classified by taxonomists?
DNA barcoding is a tool used to identify organisms that have already been classified by taxonomists. This technique involves comparing a short, standardized gene sequence from an organism's DNA to a reference database to determine its species. DNA barcoding can help quickly and accurately identify organisms, especially when traditional morphological characteristics are not sufficient.
What language do taxonomists use?
Taxonomists primarily use Latin for naming and classifying organisms. Latin is used because it is a consistent and universally understood language that helps to avoid confusion and misinterpretation in scientific communication.
Possible rationales that taxonomists might have used when deciding to group prokaryotes into two distinct domains instead of one group?
Taxonomists decided to separate prokaryotes into two distinct domains, Bacteria and Archaea, due to significant differences in their genetic makeup, cell membrane composition, and metabolic pathways. This division reflects their evolutionary divergence and highlights the unique characteristics of each domain, enabling a more accurate classification of prokaryotic species. By recognizing the distinctness of Archaea from Bacteria, taxonomists aim to capture the diversity and complexity of the prokaryotic world more effectively.
What is used as evidence for the idea of a domain Eukarya evolved from unicellular organisms?
Mitochondria and chloroplasts have their own dna

Can a message saved to your voice mail be used as evidence in small claims court in Maryland?
Yes, it doesnt matterwhat kind of evidence there is, as long as it supports your case.
Name a tool used by systematic taxonomists?
Key.
What is the modern theory of plate tectonics and what evidence is there to support it?
the modern theory is that all the continents used to be connected (Pangaea). The evidence is that the coastal boundaries fit together like a puzzle piece. another example is that the same species of animals are found on the coasts of the continents that once were touching
What kind of clothing did modern humans wear?
modern humans used lether from the animals and stitched it together to make pants,shirts and shoes.
What kind of kites were used for weather?
There are different kinds, old and modern. Read the attached article.
What kind of evidence is used to determine the relationships between animals?
Everything from where they live to body structure. Sometimes even size.
Can text messages be used as evidence?
Anything can be used as evidence if it is obtained in a legal manner. Therefrore text message can be used as evidence if the evidence was legally obtained.
